  • Thank you so much for this info. Without the diagram of the FEM unit I would not have been able to solve my central key locking problem.

  • Hello, I was wondering if you know where and what number is the fuse responsible of the driver master switch and the fuse for the idrive controller for 2014 BMW 328i XDrive.

    Thank you

  • Do you no which relay works the horn as it works sometimes so not a fuse thanks

  • I am stumped, mechanic changed out my trubo charger on my 2015 BMW 320i & took it on a test drive without bleeding the system. The car never ran out of antifreeze but did overheat a bit but never released antifreeze , the waterpump is now not getting power. I have checked all fuses, connections & battery power distribution all checked out good. I have tried to bleed the system with no luck. Please any suggestions would be greatly appreciated. Once again thank you!
